Is there any power loss over time?

Like any photovoltaic system the PV cells experience a slight degradation in power performance over their lifetimes – this is typically rated as around 0.5% loss per year, or around 10% degradation over a 20-year period. In other words, after 40 years, the PV cells will produce 80% of its day one power.

However, we believe that this degradation rate will likely be lower for the ClearVue PV strips as the PV cells are contained within and protected by the IGU glazing and are not exposed to the elements like traditional roof-based PV panels.
